Genes affected

RELN (HGNC:9957): (reelin) This gene encodes a large secreted extracellular matrix protein thought to control cell-cell interactions critical for cell positioning and neuronal migration during brain development. This protein may be involved in schizophrenia, autism, bipolar disorder, major depression and in migration defects associated with temporal lobe epilepsy. Mutations of this gene are associated with autosomal recessive lissencephaly with cerebellar hypoplasia. Two transcript variants encoding distinct isoforms have been identified for this gene. Other transcript variants have been described but their full length nature has not been determined. [provided by RefSeq, Jul 2008]

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 3251 of the RELN protein (p.Glu3251Lys). This variant is present in population databases (rs376520049, gnomAD 0.009%). This missense change has been observed in individual(s) with neurodevelopmental disorders (PMID: 31144778, 31209962). ClinVar contains an entry for this variant (Variation ID: 475996). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RELN protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The RELN c.9751G>A variant is predicted to result in the amino acid substitution p.Glu3251Lys. This variant was paternally inherited in an individual with Intellectual disability, autism spectrum disorder, and hypotonia (Table S1, Carraro et al. 2019. PubMed ID: 31144778; Table S5, Aspromonte et al. 2019. PubMed ID: 31209962). This variant is reported in 0.0093% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-103130201-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
